Question

我正在尝试使用以下两个脚本运行HSQL，然后对其进行测试，但每次出现此错误都无法处理。

执行数据库脚本失败;嵌套异常是org.springframework.jdbc.datasource.init.ScriptStatementFailedException：无法在资源类路径资源[data.sql]的第4行执行SQL脚本语句：插入spittle（spitter_id，spittleText，postedTime）值（2，'尝试使用Spring的新表达语言。'，'2010-06-11'）

更新 - 已抛出的其他异常：

完整性约束违规：外键没有父母; SYS_FK_10108 table：SPITTLE

这些是我的脚本：

schema.sql文件

drop table if exists spittle;
drop table if exists spitter;

create table spitter (
  id identity,
  username varchar(25) not null,
  password varchar(25) not null,
  fullname varchar(100) not null,
  email varchar(50) not null,
  update_by_email boolean not null
);

create table spittle (
  id integer identity primary key,
  spitter_id integer not null,
  spittleText varchar(2000) not null,
  postedTime date not null,
  foreign key (spitter_id) references spitter(id)
);

data.sql

insert into spitter (username, password, fullname, email, update_by_email) values ('habuma', 'password', 'Craig Walls', 'craig@habuma.com', false);
insert into spitter (username, password, fullname, email, update_by_email) values ('artnames', 'password', 'Art Names', 'artnames@habuma.com', false);

insert into spittle (spitter_id, spittleText, postedTime) values (1, 'Have you read Spring in Action 3? I hear it is awesome!', '2010-06-09');
insert into spittle (spitter_id, spittleText, postedTime) values (2, 'Trying out Spring''s new expression language.', '2010-06-11');
insert into spittle (spitter_id, spittleText, postedTime) values (1, 'Who''s going to SpringOne/2GX this year?', '2010-06-19');

单元测试

package com.habuma.spitter.persistence;

import org.springframework.jdbc.datasource.embedded.EmbeddedDatabase;
import org.springframework.jdbc.datasource.embedded.EmbeddedDatabaseBuilder;

public class DataAccessUnitTestTemplate {
    private static EmbeddedDatabase db;

    @Before
    public void setUp() {
        // creates a HSQL in-memory db populated from default scripts classpath:schema.sql and classpath:test-data.sql
        // obviously, this is the 'in-code' method, but the xml should work for Spring managed tests.
        db = new EmbeddedDatabaseBuilder().addDefaultScripts().build();     
    }

    @Test
    public void testDataAccess() {
        JdbcSpitterDao jdbc = new JdbcSpitterDao(db);

        System.out.println(jdbc.getSpitterById(1L));

    }

    @After
    public void tearDown() {
        db.shutdown();
    }

您的脚本以0开始ID列值。您可以指定起始值。

create table spitter (
  id int generated by default as identity (start with 1) primary key,
  username varchar(25) not null,
  password varchar(25) not null,
  fullname varchar(100) not null,
  email varchar(50) not null,
  update_by_email boolean not null
);

或者，您可以明确地插入ID：

insert into spitter (id, username, password, fullname, email, update_by_email) values (1, 'habuma', 'password', 'Craig Walls', 'craig@habuma.com', false);
